WINDOW-CLEAN ER.

SPECIFICATION forming part of Letters Patent No. 528,908, dated November6, 1894.

Application filed February 23,1894- To all whom it may concern.-

Be it known that I, ROBERT G. MITCHELL, of Huntington, in the county ofHuntington and State of Indiana, have invented certain new and usefulImprovements in Window- Oleaners; and I do hereby declare that .thefollowing is a full, clear, and exact descrip tion of the invention,which will enable others skilled in the art to which it appertains tomake and use the same, reference being had to the accompanying drawings.and to the letters of reference marked thereon, which form part of thisspecification.

This invention relates to certain improvements in brushes.

The object of the invention is to provide an improved fountain orreservoir brush particularly adapted for washing windows, and which canbe easily manipulated for this purpose so that the glass can bethoroughly washed at all corners and edges without the .reservoir orother parts carried by the brush interfering with the work.

A further object of the invention is to provide an improved brush forwashing windows so constructed and arranged that the reservoir can beeasily and quickly filled bymerely dipping the brush into the vesselcontaining the water and so that the water will not splash from thereservoir as the brush is being reciprocated when in use;

This invention consists in certain novel f eatures of construction andin combinations of parts more fully and particularly pointed outhereinafter.

Referring to the accompanying drawings, Figure 1, shows the improvedbrush in perspective, the handle thereof being broken away. Fig. 2, is alongitudinal vertical sectional view through the reservoir of the brush.Fig. 3, is a vertical cross section through the reservoir and brush.

In the drawings the reference letter a, indicates any suitable brushadapted for washing windows or like purposes. This brush is providedwith any suitable handle, such as b.

0, indicates any suitable closed water supply reservoir. This reservoiris here shown cylindrical inform, although I do not wish to limit myselfto any peculiar shape or form as the form may be made according to theshape of the brush employed. This reservoir is Serial No. 501,219. (Nomodel.)

suitably supported at a point above and in a vertical plane behind or toone side of the vertical plane of the brush so that the brush can bemoved directly up to the corner or top edge of the windowwithout dangerof the reservoir striking the window frame or other parts. The reservoiris here shown secured rigidly to the brush body by means of arms d,extending upwardly and rearward from the brush body and rigidly securedthereto and to the reservoir so as to support the reservoir in a planeabove and behind thebrush.

The water supply pipe f, extends downwardly and forwardly from thebottom of the water reservoir to the perforated distribut ing pipe e,rigidly secured on the top of the brush near the front edge thereof.This distributing pipe is rigidly secured longitudinally of the brushand is provided with perforations on its front side located over thebrushing or rubbing surface of the brush and the said pipe is preferablyof such length as to distribute water from said perforations throughoutthe entire length of the rubbing or brushing surface, such as bristles.One end of the distributing tube a, can if desired be formed open toreceive a closing plug or cork g, so that the tube can be cleaned outwhenever desired to keep the perforations always open.

A vertical tube or valve chamber h, is arranged within the waterreservoir and projects a suitable distance above the same. This tube isprovided with a cap m, having openings to permit inflow of water intothe tube and reservoir. Within the reservoir near the top thereof saidvalve chamber or tube is provided with the lateral openings 7;, into thewater reservoir for the escaping of liquid from said tube to fill thereservoir. A vertically movable float valve j, is fitted snugly in saidtube to reciprocate vertically therein and to float and to be supportedby the water in the reservoir. vided with the downwardly extending guideIt, from its under side arranged to support the valve when the water isexhausted from the reservoir and to guide the valve in its verticalmovement. This guide can be composed of a bent or looped wire if sodesired and its lower end rests on the bottom of the tube when itsupports the valve. The bottom of This valve is prothe tube is providedwith small openings Z, to prevent the formation of a vacuum beneath thevalve so that the valve will be free, to operate vertically. Thedistance between the openings 0?, and the upper end of said tubularchamber is such that when the valve is at its limit of upward movementit will rest against a suitable stop or shoulder n, and will be locatedabove the openings 2', and will thereby prevent the water in thereservoir splashing out through the top of the tube. The valve beingheld in this position when the reservoir is full by the water and as thewater gradually flows from the reservoir and its level falls it cannoteasily splash out by reason of the protecting tubes 2.

When it is desired to fill the reservoir the brush is thrust into avessel of water and as the reservoir enters the water in an invertedposition the water carries the valve up to its limit of movement by theguide 70, striking the closed end of the tube and the water flows in andfills the reservoir through the top of the tube and the openings 2'.When the brush is withdrawn from the water and held upright in itsnormal position of course the valve at once rises and closes the upperend of the tube. The water flows down through the tubef, to thedistributing pipe and passes in fine streams through the perforationsthereof to all portions of the brushing surface keeping the sameconstantly wet with clean water.

The brush can be quickly rubbed over the glass surface and the same canbe easily and quickly washed throughout its entire area, a plentifulsupply of water being furnished for all portions of the glass surface.

It is evident that various changes might be made in the forms,arrangements and constructions of parts described without departing fromthe spirit and scope of my invention.

Hence, I do not wish to limit myself to the exact construction hereshown.

Having thus fully described my invention, What I claim as new, anddesire to secure by Letters Patent of the United States, is-

1. The brush having the Water reservoir at tached thereto and arrangedto supply water to the brushing surface, said water reservoir having thesupply openings, and a float valve having guiding means and controllingsaid opening, substantially as described.

2. A reservoir brush having the vertical valve chamber arranged thereinand opening to the exterior thereof, said chamber opening into theinterior of the reservoir, and the float valve vertically movable insaid chamher, as and for the purpose set forth.

3. The reservoir brush having the water reservoir provided with thevertical tube located therein and projecting to the exterior thereof andhaving the lateral opening into the interior of the reservoir, and thevertically' movable float valve in said tube arranged to move above saidside opening when the reservoir is full and thereby prevent water fromsplashing the reservoir through the open end of the tube.

4.. The water reservoir having the vertical tube therein communicatingwith the outer air and opening into the reservoir, the verticallymovable float valve therein arranged to operate as set forth and havingthe downwardly extending guide or support from its lower side, the partsbeing arranged to operate as set forth.

In testimony that I claim the foregoing as my own I affix my signaturein presence of two witnesses.

ROBERT G. MITCHELL.
